Description of the Invention (/) This case is a fault-tolerant method and device for dial-in signal identification, especially for a dial-up function telephone < dial-in signal Identify fault tolerance methods and devices. Please refer to the first picture, which shows the connection between the phone and the switch. 'When the phone A and the phone B are talking, and the phone C wants to dial f to make a call.' The terminal will send a dial-in signal to the phone. In the current domestic practice, the dial-in signal is a voice today signal, which in turn informs the user of phone f that there is a third-party phone call for examination, and The user can use the function on the keyboard to press the chain (usually | Flash key) to switch the call status between phone B and phone C. However, this continuous sound signal severely affected the call quality between the original Zhujia and B telephones, and the users at both ends of the telephones seized the dial-in signal, which was not easy to identify, which caused considerable confusion. In countries where telecommunications are more advanced (such as the United States), the dial-in signal adopts a different approach. The dial-in signal sent by the switch is a signal that meets specific time length and frequency specifications (time length 80ms (milliseconds) ), 2130HZ / 2750HZ complex audio signal), because the strength of this signal is not strong, it is not easy to use and detect; ... so it does not affect the quality of the original call between A and B phones. Detector u (T〇ne Dector) on the signal line. Once this plug-in signal is detected (for the functional block diagram, please refer to the second figure), 'The microcontroller will be touched immediately to interrupt the phone. The sound signal received by the outside world is transmitted to the signal line for a specific time (usually set to 1 second), which means that the sound signal received by the telephone's microphone will stop transmitting to the signal line for 1 second, at this time exchange 2 This paper size applies to China National Standard (CNS) M specification (210X297 mm) (Please read the precautions on the back before filling this page) --η '----- Packing -------- Order --- „-^-\ w .-- 1 '-· Γ .------ A7

As a result, there will be no outside in this second. Voice transmission 'The letter link is online, and the exchange uses this time to transmit the telephone number of C telephone (usually transmitted after this one second) to the display on telephone A, which displays * Remind Phone A that there is a third-party phone call from time to time, and that the call between Phone A and Phone B resumes after 丨 seconds. Phone A and Phone B can still talk, and its quality will no longer be affected. The interference of dial-in signal ', and the user of telephone A can also determine whether to interrupt the call on telephone B and switch to the telephone with telephone C by the telephone number displayed on display screen 13. It also has the function of filtering the telephone. And because the plug-in signal sent by the above-mentioned parent switch end is transmitted through the signal line, it is likely to cause attenuation or noise, which will cause the original plug-in signal to be deformed. Therefore, I must tolerate a specification error. Interval (that is, the first specific time period, usually 30ms to 90ms) to compare the specifications of their dial-in signals, because if the comparison is strictly based on the time length of 80ms, the receiver will be accurately received. It is greatly reduced to an unbearable level, but relatively, the probability of misoperation is greatly increased when the error tolerance interval is too large. The most common situation is the voice signal from user B's phone or where the second phone is located. The background sound at the position has audio signals (complex audio signals of 2130hz / 275〇hz) that meet the error tolerance interval of this specification. At this time, the audio signal detector 11 (Tone Detect〇r) of the f-phone Misjudged that a dial-in signal came in and triggered the microcontroller 12 to produce a series of misoperations, such as a 1-second interruption of the sound to prepare to receive a signal representing a third party's idle call number (but it does not actually represent the first Signal of the telephone number of the person 3 As far as the paper size is concerned, the general Ning National Standard (CNS) A4 specification (210X297 male sauce) -nn I 1 In n II) wl I— II (Please read the precautions on the back before filling this page) --11 ^ ---- 0 ----: —— Γ — A7 B7 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. The invention description (3), send) and other actions that trouble users, and how to improve The above-mentioned lack of conventional technology is the main purpose of developing this case. 1 This case is a fault-tolerant method for plug-in signal identification, which is applied to a telephone with a dial-up function. The phone is electrically connected to the exchange t through the H line. The steps include: (aH tests the signal line. Debt test—the time length of the C · number is within the first specific time period and the signal is issued when it meets a special rate specification. (B) The phone transmits the sound signal received by the outside of the box because of the trigger signal. To the action of the signal line, and continuously detect the signal on the signal line to a second specific time and (C) within the first time; when the signal on the signal line is detected within a specific time, when the intensity is greater than a specific value, resume The operation of the telephone transmitting the sound 彳 § number received by the outside to the signal line. Another aspect of the case is a dial-in signal identification fault-tolerant device, which is applied to a telephone with a dial-in function. The telephone is It is electrically connected to the parent terminal through a line ^. Its identification device includes: an audio signal debt. The J device is electrically connected to the line 彳 §, which is used to detect the signal line. Long signal time A trigger signal is issued when it is within a first specific time zone and meets the special frequency specification; a microcontroller is electrically connected to the audio signal detector, which interrupts the telephone set in response to the trigger of the trigger signal The action of transmitting the sound signal received from the outside to the signal line, and sends out a repeated determination signal; two amplitude detection devices, which are electrically connected to the signal line and the pole controller, should be re-determined and continue to detect The signal on the signal line is measured for a second time. When the signal amplitude of the signal line is detected to be greater than one within the second specific time, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). ) (谙 First read the precautions on the back and then fill out this page) -Install. Π Ⅴ. Description of invention (thousands) A7 B7 When a specific value is issued, a recovery signal is issued to trigger the microcontroller to restore the phone The action of transmitting the sound signal received by the outside to the signal line. In this case, it can be determined that the received signal is the sound signal of the telephone user of the caller or the back of the location. Sounds, etc., instead of the insertion signals actually sent by the switch, can avoid a series of malfunctions caused by accidentally touching the controller 12, and completely improve the lack of conventional methods. This case can be obtained by the following diagram and detailed description. Go deeper into the winter. I understand the first picture: it is a schematic diagram of the connection between the three telephones and the exchange. The second picture: it is a schematic diagram of the functional block of the plug-in function telephone. The third circle: it is the preferred embodiment of this case. The functional blocks are schematic. The components included in the diagram in this case are listed as follows: Signal line 10 Audio signal detector U Microcontroller 12 Display screen 13 Signal line 20 Audio signal detector 21 Amplitude detection device 22 Microcontroller 23 altar display 24 〇 Printed by the Consumer Cooperative of the Central Government Bureau of the Ministry of Economic Affairs, please refer to the third figure, which is a functional block diagram of the preferred embodiment of the case, which is composed of an audio signal detector 21 and an amplitude detection device 22 , Microcontroller 23. I take the three telephone architecture shown in the first picture as an example to illustrate the technical means. When the audio signal detector of telephone A has 5 paper sizes, it is applicable to the Chinese national kneading rate (CNS) A4 specification (210X297 mm) 21 (T one Detec 101 ·) detected on the signal line 2 σ to 1 After the time length of the signal meets the specification error tolerance interval (that is, a specific time period, usually 30ms to 90ms), a trigger signal is sent immediately to trigger the microcontroller 23 to interrupt the telephone that the telephone will receive from the outside. The operation of transmitting the sound signal to the horn line (that is, the sound signal received by the microphone of the telephone A will stop transmitting to the signal line), and the signal is repeatedly sent to the amplitude detection device 22. The amplitude detection device 22 should continuously detect the signal on the signal line for a second specific time (about 10ms) because it should determine the scale of the signal again. Whether the amplitude intensity is greater than a specific value. Because the real king transmits an interruption signal from the switch side, the switch side also prevents the voice signal of telephone B from being sent to the telephone line of telephone A within a certain time (usually 丨 seconds), so as not to interfere with the telephone call of telephone C Transmission of number signals. Therefore, if it is really an interruption signal transmitted by the switch end, the amplitude detection device 22 will listen to the received signal within 10ms and the scale will be close to zero, and it will be larger than the preset specific value. The dial-in signal judged to be true 'continues to perform subsequent actions such as waiting for the transmission of telephone C's phone number. However, if the trigger signal of the audio signal detector 21 is a sound signal sent by the user of phone B, or the background sound of the location where phone B is located, etc., is not really a plug-in signal issued by the line terminal, At this time, the voice signal of the second telephone set will not be transmitted. The first telephone signal line will not be interrupted. Therefore, the amplitude detection device is installed. 2 The signal received between the two sides is amplified and detected. The intensity must be at that particular value. At this time, the amplitude detection device 22 sends two recovery signals, triggering the 徼 controller to resume the telephone to transmit the sound signal received by the outside world to the description of the invention («the action of the line, stop preparing to receive the action of the person on behalf of n. To avoid false contact with the gangliner 12 == the lack of conventional means to improve the basic method. According to the above, this case can determine that the received signal is the voice signal of the caller using f or the background sound of riding on the position. Rather than the dial-in signal sent by the switch, this can avoid a series of misoperations that will cause trouble to the user, and the lack of methods to improve the practice. This case was created by people who are familiar with this skill. Modifications, but none can be separated from the soft protectors attached to the patent application park.
